Honestly, the bootleg recording of the song isn't that impressive. I mean I'm a huge fan of the first couple Priest records, but this live recording of Mother Sun from 1975 is a bit shaky and rough to listen to. The band Portrait recently recorded a cover version of the song, and their version is actually quite a bit better. Still, I needed the Priest live version in my collection, so I grabbed the bootleg LP.
As a whole, this is a really good bootleg. Side one is just a killer recording of Priest live in the BBC studio from 1978. That opening riff for White Heat, Red Hot is fucking killer and it is nice to hear a live version of Starbreaker. Side two has the two songs that the band recorded for the Old Grey Whistle Test...and while I've seen the live videos for those songs on youtube, it is cool to have them here.
